Express the speed in km/h also. The time period of this simple pendulum is [NCERT Exemplar] Since, the distance-time graph of the object D is not a straight line, therefore, its motion is non-uniform. (v) Not correct (c) a straight line inclined at some angles towards x-axis An object can move with constant or variable speed. Question 16. Briefly explain how will decide which object is moving fast and which one is moving slow. The circumference of the circle traced by the second hand is 64 cm. (d) None of the above Answer: Which of the following statement is correct for these clocks? (b) Briefly mention the values showed by Chintoo’s mother here. Question 3. Answer: Time taken by the car =. So, for 365 days, we have 24 × 365 h = 8760 h. Question 13. (b) straight line parallel to x-axis Question 3. Describe a simple pendulum. Here on AglaSem Schools, you can access to NCERT Book Solutions in free pdf for Science for Class 7 so that you can refer them as and when required. (iv) Not correct State how do we measure time interval of a month. 10. (iii)Circular motion Answer: Science Class - VII. Match the Columns Register online for Science tuition on Vedantu.com to score more marks in your examination. (c) km/h. This is Science Class 7 Motion and Time CBSE Questions & Answers. Therefore, it has a motion along a straight line.
